Applications

This data is based on LD43G-C1-500-LW30-NB

*Lumen output data applies to all colour temperatures

** I

ndicates the nominal power for the LED run at that particular current and includes losses associated with using an 85% efficient driver

***UGR values based on room parameters of 4H 8H, C70 W50 F20

LD43A and LD43W lumen output will be 40% less due to the glare shield - LD43R lumen output will be 77% less - LD43AR lumen output will be 73% less
